SAND CONTROL METHOD AND APPARATUS

摘要

A well completion is provided to enable sand-control treatment of one or more production zones (42, 44) with only a single trip into a well. In one example arrangement, the completion may include a first (12), second (20) and third (36) packer. The first packer (12) may be attached to a production tubing (40). A first sand screen (16) may be disposed between the first (12) and second (20) packers. A first closing sleeve (14) may be disposed between the first (12) packer and the first (16) sand screen. A first surface controlled flow control device (18) may be disposed between the first sand screen (16) and the second packer (20). A control conduit (38) extending from the earth's surface is sealably passed through the first (12) packer and connected to the first surface controlled flow control device (18). A second sand screen (24) is disposed between the second (20) and third (36) packers. A second closing sleeve (22) may be disposed between the second packer (20) and the second sand screen (24). A second surface controlled flow control device (26) may be connected to the control conduit (38) and disposed between the second sand screen (24) and the third packer (36). The first sand screen (16) may be disposed within the well proximate a first production zone (42) and the second sand screen (24) may be disposed within the well proximate a second production zone (44).
